Download or read book Reduced Worker Exposure and Improved Energy Efficiency in Industrial Fume hoods Using an Airvest written by and published by . This book was released on 1992 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reduction in the breathing zone concentration of an experimentally simulated pollutant, by factors ranging from 100 to 800, was observed with the device (called an airvest). With use of the airvest by the worker, the hood face velocity can be reduced, leading to substantial energy savings in conditioning of make up air in the building. The airvest works by elimination or ventilation of the eddy that develops in front of a worker when the worker stands in the open face of a fume hood. Normally this eddy draws some of the pollutant (commonly generated near and in front of the worker) towards the worker's breathing zone. Experiments sing a heated full-size mannequin were conducted with a full scale walk-in fume hood. Sulfur hexafluoride was used to simulate pollutant generation and exposure during a work situation. Flow visualization with smoke was also undertaken to evaluate the airvest qualitatively. 3 refs.

Download or read book Energy Efficient Laboratory Fume Hood written by and published by . This book was released on 2000 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The present invention provides a low energy consumption fume hood that provides an adequate level of safety while reducing the amount of air exhausted from the hood. A low-flow fume hood in accordance with the present invention works on the principal of providing an air supply, preferably with low turbulence intensity, in the face of the hood. The air flow supplied displaces the volume currently present in the hood's face without significant mixing between the two volumes and with minimum injection of air from either side of the flow. This air flow provides a protective layer of clean air between the contaminated low-flow fume hood work chamber and the laboratory room. Because this protective layer of air will be free of contaminants, even temporary mixing between the air in the face of the fume hood and room air, which may result from short term pressure fluctuations or turbulence in the laboratory, will keep contaminants contained within the hood. Protection of the face of the hood by an air flow with low turbulence intensity in accordance with a preferred embodiment of the present invention largely reduces the need to exhaust large amounts of air from the hood. It has been shown that exhaust air flow reductions of up to 75% are possible without a decrease in the hood's containment performance.

Download or read book Emerging Chemical Risks in the Working Environment written by Małgorzata Pośniak and published by . This book was released on 2023-05 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Around the world, the production and use of nanomaterials, as well as carcinogenic, mutagenic, reprotoxic substances (CMR) and endocrine disruptors has systematically increased. The increase in production has exposed workers to hazardous substances in practically all branches of the world economy. Readers will have access to up-to-date and comprehensive knowledge on emerging risks related to nanomaterials, endocrine disruptors, reprotoxic, carcinogenic and mutagenic substances, which are related to the development of technologies and workplaces. The book will provide the tools for occupational risk assessment of chemical substances for which there are no safety levels of exposure as well as an indication of methods and measurements to protect human health and reduce chemical risks at the workplace. This book creates awareness for employers, employees and safety experts about emerging risks related to chemical agents resulting in the reduction of cancer, reproductive system diseases, cases of abnormal child development, hormonal system disorders leading to abnormal metabolism, obesity, and diabetes. Features: Comprehensive information on emerging and newly identified chemical hazards Delivers the latest data on methods and tools for identification, assessing and reducing health risks Provides practical occupational safety advice and recommendations Real life examples from measurements carried out in the workplaces "The monograph, due to the high universality of its considerations, can be addressed to a very wide audience. It is an important compendium of knowledge, which can be used by health and safety services, employers, people designing new technologies and those interested in this issue. It is a valuable and up-to-date study, among others because it uses the latest literature and quotes current legal acts." --Slawomir Czerczak, Nofer Institute of Occupational Medicine, Poland

Download or read book Air Quality Management written by Ronald E. Hester and published by Royal Society of Chemistry. This book was released on 1997 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: The management of air quality is currently at the forefront of international debate. With authors drawn from international experts in their respective fields, Air Quality Management provides comprehensive coverage of the air quality management issue. There are chapters on improving air quality in the UK, the construction of emissions inventories and the design and operation of air monitoring networks. Validation of air pollution models, requiring source receptor modelling, is described, as is the use of geochemical or biological tolerances known as critical loads to determine the maximum allowable inputs of pollutants to the terrestrial environment. The first European Auto-Oil Study, which was sponsored by the European Commission in order to identify the most cost-effective means of meeting air quality targets, is included as a case study. There is also reference to the successes and problems of air pollution control in California, the US state which has pioneered the promotion of vigorous air pollution control measures. Air Quality Management provides a vital source of material for all those involved in the field, whether as a student, industrialist, consultant, or government agency with responsibility in this area.
